SPOOL-FRAME FOR LOOIVIS FOR WEAVING TUFTED FABFHCS.

SPECIFICATION forming part of Letters Patent No. 783,277, dated February 21, 1905.

Application filed June 24, 1904. Serial No. 214,066.

To (LZZ 7.072.012, it Tmty concern.-

Be it known that I, JAMEs PERCIVAL HUM- PHRIES, director, asubject of the King of Great Britain whose address is The Carpet Factories, Kidderminster, in the county of Worcester England, have invented certain new and useful Improvements in Spool-Frames for Looms, of which the following is a specification.

In a loom for weaving a tufted fabric, such as an Axminster carpet, spool-frames are used to carry the spools upon which are wound the different yarns, these frames being carried into use in the loomupon carrying-chains.

The present invention comprises the hereinafter described and claimed improvements in a spool-frame, whereby in a simple and effective manner bearings are made in the ends of the frame for the pivots or arbors of the spool and a retarding friction is provided to the too free rotation of the said spool.

The improvements will be made clear by the annexed drawings, upon which Figure l is a longitudinal elevation of a spool-frame and spool; Fig. 2, an enlarged elevation, part section, of one of the ends of Fig. 1; and Fig. 3, a transverse section of Fig. 2 on the dotted lines looking to the left.

In the drawings both ends of the spool and spool-frame are provided with the improvements; but the one end only may be so provided, with the other end constructed as ordinarily.

The spool-frame is composed of a wood body part 0, end brackets c c, rigidly secured to said body part, and yarn-feeding tubes (Z, also secured rigidly to said body part. The said securing is at the ends of the body part assisted by metal ferrules e e, which bind the wood ends against splitting and which form a more rigid substance for the brackets and tubes to be screwed or nailed to. Each bracket 0 has a spring-arm c fitted to it, to constitute, with the bracket, a means for connecting the spoolframe to its carrying-chains, (not shown,) this means being a well-known one. A feature,

however, of the brackets c 0 is that they do not carry rigid bearing-holes for the arbors of the spool g, which is carried upon the spool-frame to rotate.

The arbors 1 find their bearing-holes in spring-formed limbs /1 /1.,(preferably of metal,) which at their one ends are securely attached to the ends of the spool frame inside the brackets 0 c and which at their other and free ends bear with pressure against the outer faces g g of the ends of the spool. Each limbspring 71. is alike in construction, in its attachment to the end of the spool-frame, and also in its manner of engaging and disengaging the spool-arbors, so that a description of one of them Will suflice. As seen from Figs. 2 and 3, the spring-limb it is rigidly secured at its one end, if, to the end (L2 of the spool-frame by the help of the ferrule and that at its other and free end, /L3, is formed with a bearing-hole m for the reception of the arbor g of the spool, this arbor, which is immovable upon the spool working in said hole m for a bearing, the spool being thereby supported from the spool-frame by said spring-limb. The free end 7? of the spring-limb it is adapted to bear against the face g of the spool with sufficient pressure to create the necessary amount of friction to prevent the spools too free rotation, thereby keeping the yarn fed into the tubes (Z from loose feeding.

To connect and disconnect the spool to and from the spool-frame, all that is necessary is to pull the freeend ]L3 of the spring-limb it toward the bracket 0 and away from the spool end, (as represented in dotted lines at 0,) when the bearing-hole on will be pulled off and clear of the spool-arbor for which purpose there is on the free end A provided a finger-grip n. The connection and disconnection of the spool to and from the spool-frame puts the springlimb it into further tension, it, however, when in the position represented in Fig. 2 always having sufficient power at its free end to put a braking friction upon the end of the spool.

Thus it Will be seen that the spring-limb It has two functions the one to form a bearing for the arbor of the spool and the other to press upon the end of the spool to create between the said end and itself a braking friction to the too free rotation of the spool, the connection and disconnection with the use of the spring-limb not necessitating a push-in arbor g.

The bearing-hole m in the spring-limb /1 is preferably slightly thicker than the thickness of the spring-limb, this thickness being easily obtainable by displacing the metal after the punching of the bearing-hole into a very short tube-like piece.

To make the spring-limb it more rigid laterally, the fixed end A may be let into an end gap 6 in the ferrule; but the said limb can be otherwise laterally fixed may be to the bracket cit only being necessary to so provide the said spring-limb that its free end can be pulled toward the bracket 0, as the dotted lines 0 represent.

Having noW described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a loom, the combination of a spoolframe, yieldablelimbs carried at opposite ends thereof, a rotatable spool having immovable arbors supported by the said limbs, said limbs adapted to frictionally engage the outer faces of the said spool, and automatic means for connecting the spool-frame to the loom.

2. In a loom, the combination of a spoolframe, yieldable limbs mounted on the outer ends of the said frame, a rotatable spool having immovable arbors supported by the said limbs, said limbs adapted to frictionally engage the outer faces of the spool, and a locking device for securing the frame to the loom.

3. In a loom, the combination of a spool- .frame, laterallyyieldable limbs detachably connected to the frame, a rotary spool having limbs frictionally engaging the outer faces of said spool, and fixed yarn-guiding tubes on said spool-frame.

5. In a loom, the combination of a spoolframe having fixed yarn -guiding tubes, a rigid limb at one end of said frame, a yieldable limb at the opposite end thereof, a spool provided with immovable end arbors mounted between the said limbs and supported thereby, the same being in frictional contact with the spool, and means for connecting the spoolframe to the loom.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
